摘要：
Compressed video is well known to be self-similar in nature. We model VER carrying long-range dependent, multiplexed MPEG-2 video sources traffic. The actual traffic for the model is generated using fast-fourier transform of the fractional gaussian noise sequence. Our model of compressed video sources bears similarity to an MPEG-2 transport stream carrying video, i.e., it is long-range dependent and generates traffic in a piecewise constant bit rate manner: We study the effect of such VER traffic on ABR carrying TCP traffic. The effect of such VER traffic is that the ABR capacity is highly variant. We find that a switch algorithm like ERICA+ cart tolerate this variance in ABR capacity while maintaining high throughput and low delay. We present simulation results for terrestrial and satellite configurations.
